INSULATING MATERIAL. Application filed July 26, 1926. Seria1.No. 124,885.

My present invention has for its object but showing a slight modification of the 55 to provide an extremely simple and highly insulating material;

. cfiicient insulating material adapted for Fig.4: is an edge view of the insulating general use, but especially adapted as a submaterial shown inFig. 3, partly collapsed;

stitute for back plaster in dwellings or buildand ings. This insulating material is made up Fig. 5 is a fragmentary detail view show- 60 of a plurality of correlated sheets having ing one of the flaps of the insulating matesubstantially parallel and perpendicular rial shown in Figs. 1, 2 and 5. portions, the latter serving to space said For the purpose of howing the insulating parallel portions and form attaching flaps. material applied in position there is illus- Said sheets at the joints between their trated in the drawings one of the walls of a parallel and perpendicular portions are building which comprises studdings 6, sheetscored to afford folding lines. The several ing 7 and lath and plaster 8.

The formation of 10 indicate respectively inner and outer the insulating material is such that it may sheets having substantially parallel portions be collapsed and folded in flat position when ,and perpendicular portions, the latter servcarried in stock and the sheetsthereof may ing to space said parallel portions and form be of ordinary paper, tarred felt of different attaching flaps 11.

The purpose of portions of the sheet 10 are wider than the scoring the sheets, forming the insulating perpendicular portions ofthe sheet 9 so as to material, at their 'oints 18 -to cause the laterally space the substantially parallel por- 30 parallel and perpendicular portions of said tions of the insulating material.

The perpendicular portions of studdings 6, and the flaps 11 bear on the one sheet are wider than the perpendicular opposing faces of said studdings and are 35 portions of the other sheet so as to hold the secured thereto by lath 14 secured to said parallel portions of the sheets laterally studdings by. nails 15. The substantially spaced when the insulating material is parallel portions of the sheets 9 and 10 are secured to and between the stu dings. These connected and laterally spaced at the intersheets of the insulating material are also mediate portions by a Z-shaped web 16 the 40 laterally spaced from the walls of the buildend portions of which are glued to the opposing and divide the space therebetween into ing faces of said sheets and said web is a plurality of air spaces. scored at 16' in its joints to cause said web The invention is illustrated in the accomto readily fold with the insulating material. anying drawings wherein like characters By reference to Fig. 2 it will be noted when 45 indicate like parts throughout the several the insulating material is collapsed one of views. the flaps 11 is folded directly on to the Referring to the drawings: parallel portions of sheets 9 and 10 and the Fig. 1 is a view in horizontal section showother flap 11 extends outward in the same i in one form of thefinsulating material plane with said sheets.

It is, of course, understood that the above described insulating material is placed in a building before the lath and the plaster is applied.

What I claim is:

1. An insulating material made up of a plurality of correlated sheets having substantially parallel and perpendicular portions forming a parallelogram, said perpendicular portions serving to space said parallel portions, said sheets having extensions aflording attaching flaps.

2. The structure defined in claim 1 in perpendicular porinto position between said tions of the sheets are flexibly connected-t0 permit saidmaterial to be collapsed and folded in fiat condition.

3. The structure defined in claim 1 in further combination withalongitudinal s acing web attached to the parallel portions of said sheets and connecting the same.

4. The structure defined in claim 1 in further combination with a longitudinal spacing web attached to the parallel portions of said sheets and connecting the same and to which the parallel and perpendicular portions of the sheets are flexibl connected to permit said material to be collapsed and folded in flat condition.

5. The structure defined in claim 1 in which said sheets are scored in the joints between their parallel and perpendicular portions.

6. The structure defined in claim 1 in which said sheets are permanently connected at their attaching flaps.

In testimony whereof I affix my signature.
